An update that solves 13 vulnerabilities and has four fixes

is now available.

 

Description:

 

 

This update for qemu fixes several issues.

 

These security issues were fixed:

 

- CVE-2017-2620: In CIRRUS_BLTMODE_MEMSYSSRC mode the bitblit copy routine

cirrus_bitblt_cputovideo failed to check the memory region, allowing for

an out-of-bounds write that allows for privilege escalation (bsc#1024972)

- CVE-2017-2615: An error in the bitblt copy operation could have allowed

a malicious guest administrator to cause an out of bounds memory access,

possibly leading to information disclosure or privilege escalation

(bsc#1023004)

- CVE-2017-5856: The MegaRAID SAS 8708EM2 Host Bus Adapter emulation

support was vulnerable to a memory leakage issue allowing a privileged

user to leak host memory resulting in DoS (bsc#1023053)

- CVE-2016-9776: The ColdFire Fast Ethernet Controller emulator support

was vulnerable to an infinite loop issue while receiving packets in

'mcf_fec_receive'. A privileged user/process inside guest could have

used this issue to crash the Qemu process on the host leading to DoS

(bsc#1013285)

- CVE-2016-9911: The USB EHCI Emulation support was vulnerable to a memory

leakage issue while processing packet data in 'ehci_init_transfer'. A

guest user/process could have used this issue to leak host memory,

resulting in DoS for the host (bsc#1014111)

- CVE-2016-9907: The USB redirector usb-guest support was vulnerable to a

memory leakage flaw when destroying the USB redirector in

'usbredir_handle_destroy'. A guest user/process could have used this

issue to leak host memory, resulting in DoS for a host (bsc#1014109)

- CVE-2016-9921: The Cirrus CLGD 54xx VGA Emulator support was vulnerable

to a divide by zero issue while copying VGA data. A privileged user

inside guest could have used this flaw to crash the process instance on

the host, resulting in DoS (bsc#1014702)

- CVE-2016-9922: The Cirrus CLGD 54xx VGA Emulator support was vulnerable

to a divide by zero issue while copying VGA data. A privileged user

inside guest could have used this flaw to crash the process instance on

the host, resulting in DoS (bsc#1014702)

- CVE-2016-10155: The virtual hardware watchdog 'wdt_i6300esb' was

vulnerable to a memory leakage issue allowing a privileged user to cause

a DoS and/or potentially crash the Qemu process on the host (bsc#1021129)

- CVE-2017-5526: The ES1370 audio device emulation support was vulnerable

to a memory leakage issue allowing a privileged user inside the guest to

cause a DoS and/or potentially crash the Qemu process on the host

(bsc#1020589)

- CVE-2017-5525: The ac97 audio device emulation support was vulnerable to

a memory leakage issue allowing a privileged user inside the guest to

cause a DoS and/or potentially crash the Qemu process on the host

(bsc#1020491)

- CVE-2017-5667: The SDHCI device emulation support was vulnerable to an

OOB heap access issue allowing a privileged user inside the guest to

crash the Qemu process resulting in DoS or potentially execute arbitrary

code with privileges of the Qemu process on the host (bsc#1022541)

- CVE-2017-5898: The CCID Card device emulator support was vulnerable to

an integer overflow allowing a privileged user inside the guest to crash

the Qemu process resulting in DoS (bnc#1023907)

 

These non-security issues were fixed:

 

- Fix post script for qemu-guest-agent rpm to actually activate the guest

agent at rpm install time

- Fixed various inaccuracies in cirrus vga device emulation

- Fixed cause of infrequent migration failures from bad virtio device

state (bsc#1020928)

- Fixed virtio interface failure (bsc#1015048)

- Fixed graphical update errors introduced by previous security fix

(bsc#1016779)

- Fixed uint64 property parsing and add regression tests (bsc#937125)
